I would recommend putting the logging handler before the
FaultContractExceptionHandler. Then you would see the StackTrace of the original exception instead of the information about the newly created, but not yet thrown, FaultContractWrapperException. Since the FaultContractWrapperException
is not yet thrown it does not have a StackTrace.

Also, I think everyone would find it easier to read the post if the configuration was formatted using the Insert Code Snippet functionality. Thanks. :)

I wasn't laxing but the insert code pop up never works for me. I've tried on chrome, ie9. after pasting the config/code & when i click insert, the reply window is always empty. in other words, the code is never pasted to this window

this behaviour has been like this for over weeks now for me. I wanted to raise a bug but wasn't sure where I can.
